Jon Morosi of FOX Sports tweeted that the Cardinals and Red Sox are in active trade talks regarding Boston starter Jake Peavy. However, Derrick Goold of the St. Louis Post-Dispatch said that St. Louis is "looking for offense, not Peavy." According to Pete Abraham of the Boston Globe, Atlanta has also had discussions with Boston about Peavy. Abraham also noted that the Red Sox have been in talks with several teams regarding their pitchers – not just Peavy.

Ken Rosenthal wrote that he would not be surprised if Rockies shortstop Troy Tulowitzki asked for a trade this offseason. Rosenthal cited Tulowitzki's desire to play for a winner and his frustrations over Colorado's inability to put together a playoff-caliber pitching staff.

The Indians have placed Opening Day starter Justin Masterson on the 15-day disabled list with knee inflammation. Masterson has struggled mightily this season and has said that his knee issue has been bothering him since early in the season.

Along with placing Masterson on the DL, Cleveland designated reliever Mark Lowe for assignment, sent outfielder Tyler Holt and Triple-A, and called up reliever Nick Hagadone and catcher Roberto Perez.

Carlos Santana jammed his shoulder making a diving play at first base in Monday night's game. Santana was given the night off in the field on Tuesday, but Terry Francona has said that he will be fine.
